Latest 10 year treasury mortgage rate spread reading shows a 1.94-point gap as of May 26 2026, with the 30-year fixed at 6.51% and the 10-year Treasury at 4.57%.
As of the most recent FRED data release covering May 21, 2026, the 30-year fixed mortgage rate stood at 6.51% while the 10-year Treasury yield printed 4.57%. That produces a spread of 1.94 percentage points. Earlier in the week, the 10-year Treasury averaged 4.48% and the 30-year mortgage 6.36%, narrowing the gap to 1.88 points. Both readings sit comfortably inside the long-term 1-to-2-point band that has prevailed since the post-pandemic normalization period.
The 10 year treasury mortgage rate spread captures the additional compensation investors demand for holding 30-year mortgage-backed securities instead of the 10-year Treasury note. The difference reflects credit, prepayment, and liquidity risk premia that are absent from Treasuries. When the spread compresses, mortgage rates fall faster than Treasury yields; when it widens, borrowers feel the impact even if the 10-year yield is unchanged.
Treasury yields experienced notable volatility in March 2026 after geopolitical events pushed the 10-year yield from a low near 4.39% to 4.96% on the long end. Mortgage rates responded by climbing toward 6.5%, according to contemporaneous market reports. By late May the 10-year had settled back to 4.57%, allowing the 30-year fixed to ease modestly while the spread remained anchored near 1.94 points.
A separate weekly series showed the mortgage-Treasury spread at 201 basis points for the week ending January 9, 2026, down from 209 basis points the prior week. That narrowing occurred even as absolute rate levels stayed elevated, illustrating how spread dynamics can diverge from headline yield moves.
Over the past decade the 10 year treasury mortgage rate spread has rarely traded outside the 1.00–2.00 point corridor except during acute liquidity events. The 2022–2023 tightening cycle briefly pushed the spread above 2.5 points before mean-reverting. Current levels near 1.9 points therefore remain consistent with a market that prices normal credit and prepayment risk without signaling stress.
While national averages dominate headlines, local pricing can differ. In the Atlanta metro, conforming 30-year rates averaged 6.48% on May 21, 2026—three basis points below the national 6.51% print. In the Seattle metro the same product carried a 6.59% note rate, four basis points above the benchmark. These small deviations reflect varying originator capacity and investor demand for loans from each region rather than changes in the underlying 10 year treasury mortgage rate spread.
Several structural factors keep the spread from collapsing further. Lenders continue to face higher servicing costs and regulatory capital charges than in the pre-2020 environment. In addition, the ongoing mix of cash-out refinances and investor-owned properties introduces modestly higher prepayment and credit risk than the all-purchase, owner-occupied pools common before the pandemic.
A stable 1.9-point spread suggests that further declines in the 10-year Treasury yield would translate almost one-for-one into lower mortgage rates. Conversely, any renewed backup in yields would lift borrower costs without an offsetting spread compression. Market participants monitoring weekly FRED updates can therefore treat the 10 year treasury mortgage rate spread as a reliable transmission channel rather than an independent variable.
With the 30-year fixed at 6.51% and the 10-year Treasury at 4.57%, the 10 year treasury mortgage rate spread sits at 1.94 points— squarely inside its historical range.
